4.18 Misoperation prevention and parameter setting restriction

Purpose
Limits reset function
Trips when PU is disconnected
Stops from PU
Prevention of parameter rewrite
Prevention of reverse rotation of the motor
Displays necessary parameters
Parameter restriction with using
password
Control of parameter write by
communication

4.18.1 Reset selection/disconnected PU detection/PU stop selection (Pr. 75)

You can select the reset input acceptance, disconnected PU (FR-PU04/FR-PU07) connector detection function and PU
stop function.

PU stop selection
The above parameter can be set when Pr. 160 Extended function display selection = "0". (Refer to page 197)
This parameter allows its setting to be changed during the operation in any operation mode even if "0" (initial value) is set in Pr. 77 Parameter write
selection. This setting does not return to the initial value even though the (all) parameter clear is performed.

Reset Selection
Setting
0 Reset input normally enabled

occurs.
16 Reset input normally enabled
Reset input is enabled only when the fault
17
occurs.
(1) Reset selection
You can select the enable condition of reset function (RES signal, reset command through communication) input.
When Pr. 75 is set to any of "1, 3, 15, 17", a reset can be input only when the inverter is tripped.
NOTE
 When the reset signal (RES) is input during operation, the motor coasts since the inverter being reset shuts off the output.
 When reset is performed, cumulative values of electronic thermal O/L relay, and regenerative brake duty are cleared.
 The reset key of the PU is only valid when the inverter is tripped, independently of the Pr. 75 setting.
